6 FAQs about [Inverter reports reference voltage error]

What are common error codes on inverters?

Modern inverters come equipped with digital displays that show error codes when something goes wrong. Here’s how to address common error codes: Low Voltage Error: Indicates that the battery voltage is too low. Charge the battery and reset the inverter. Overload Error: Reduce the connected load to within the inverter’s rated capacity.

What are the most common faults on inverters?

In this article we look at the 3 most common faults on inverters and how to fix them: 1. Overvoltage and Undervoltage Overvoltage This is caused by a high intermediate circuit DC voltage. This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage.

What causes an inverter overvoltage error?

The inverter overvoltage error can also be caused by the inverter’s load in the form of a large inertia load, which can cause the motor to become a generator that generates electricity back to DC causing OV condition. You can recognize this error because it only occurs when the drive starts or stops. For this reason, there are 2 ways to fix it:

How to check if an inverter is overvoltage?

Then measure the input voltage or check the DC bus parameter at fault (you can check this parameter in the monitor parameter set of the inverter). Input overvoltage of the inverter is usually caused by a problem with the substation that increases the voltage at the inverter power supply.

What causes a DC inverter to overvoltage?

This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on. Check supply voltage for constant or transient high voltage. Increase deceleration time.

What are ABB inverter error codes?

In the first group of ABB inverter error codes, an error message and an LED display are shown, but no alphanumeric code is displayed. The codes, possible causes, and solutions are as follows: Ground fault in the photovoltaic generator due to a leaked current on the system’s DC side. Measure the insulation resistance.
